rndis_host: support WM6 devices as modems
This patch allows Windows Mobile 6 devices to be used for tethering -- that is, used as modems. It was requested by AdamW in kernel bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=11119 and Mandriva kernel-discuss list. It is tested and confirmed to work by Peterl: http://forum.eeeuser.com/viewtopic.php?pid=323543#p323543 This patch is based on the patch in the above kernel bugzilla, which is from the usb-rndis-lite tree.
